Piromidic acid is primarily used as an antibacterial agent, particularly in the treatment of urinary tract infections (UTIs). It works by inhibiting bacterial DNA replication, making it effective against a range of gram-negative bacteria commonly responsible for such infections. Its application is often seen in oral formulations, where it is administered to patients to alleviate symptoms and eradicate the infection. Due to its targeted action, it is considered a useful option in cases where other antibiotics may be less effective or contraindicated. Additionally, it has been studied for its potential use in veterinary medicine to treat bacterial infections in animals.
